ARRIS' flagship cable modem termination system (CMTS), the Cadant C4, has become the latest product to win the coveted DOCSIS 2.0 qualification stamp from CableLabs, following results from certification wave 29.
ARRIS' chassis-based product is just the third CMTS to obtain DOCSIS 2.0 qualification. ARRIS' "pizza-box" CMTS, the C3, won that distinction in April, following testing wave 28. Terayon Communication Systems' BW 3500 was the first CMTS to gain 2.0 qualification.
CableLabs also granted DOCSIS 2.0 certification to modems from Ambit, Linksys and Thomson, and re-certified products from Conexant Systems (two modems), Motorola Broadband and Scientific-Atlanta (two modems).
CableLabs also qualified CMTSs from Motorola and BigBand Networks for DOCSIS 1.1. BigBand Networks recently purchased ADC's CMTS assets.
Cable's Colorado-based R&D house said wave 29 marked the first time that all submitted DOCSIS devices passed certification or qualification in a single testing wave.
In other certification news, CableLabs awarded CableHome 1.1 status to two Linksys-made cable modem gateways.
CableLabs is expected to release results from certification wave 30 on or around Aug. 18.
